The nTune release notes for version 5.05.25.00 confirm the product's existence, and when we asked NVIDIA directly, they told us it will be available for roughly ~£50, so you should expect products to be available in the 70-80€ price range most likely. This is a fairly significant price cut compared to the 650i SLI, since that seems to retail for about 100 to 120€. A quick Froogle tells us that the cheapest 650i SLI available at UK E-tailers sells for £68, including VAT.
